Suggestions for first time water cooling system

post #1 of 8
Thread Starter 
Hey guys,
I have never used liquid cooling but I think I want to make the jump from air to liquid cooling. What is a good cooling kit to get to cool both the CPU and GPU?

I've heard great things about the rasa kits. You get a great block at a great price, and is easily expandable. Although, for ultimate performance, I'd go with a custom build personally. There's plenty of used CPU blocks on sale here, and quite honestly, used blocks are just about as good as new ones, just sometimes not as pretty. Your gpu block is where it gets expensive though. For a CPU only loop, you can get a great one for $150 to $200, but adding in the gpu block adds another $100+.

You can get some info from the RASA kit page here:

http://www.overclock.net/water-cooli...-rs-rx120.html

You can look at some of the FAQs there or if you have questions about their kits you can post there. The best kit you could get is the RX360 kit but you gotta make sure your case can fit it (unless you plan on mounting it outside or modding your case).

The kit comes with just about everything except liquid and biocide/silver (something to stop growth in the water). Those can be bought very cheaply online/locally.

The stickies contain a vast amount of information, well worth a read through.

The Rasa kit will be great with some extra GPU blocks, but it depends on how many and what type of GPUs you have as to if the RX360 rad (best available in the kits) will cope. You might need more rad.

As a rough guide, for a custom loop you will need:

Pump: MCP35x, MCP355, EK DCP 4.0 (aka DD CPX Pro), MCP 655 (better for shorter loops).

Pump top: The 355 does a lot better with an after market pump top, worth getting if you are running a separate res. If you are running a pump res combo then...

Reservoir: Personal preference, bay res or tube, decorative or plain, pump mounted or not. You can get combined pump tops and reservoirs for the MCP 355, 35x and 655.

Radiator: For CPU and 1 GPU, min 360mm of rad, for CPU and 2 GPUs, min 480mm of rad (rough estimate, depends on your GPU and desired fan speed). Black Ice SR1 or XSPC RX for low speed fans, Swiftech MCR for price / performance, Black Ice GTX for high speed fans.

Fans: Scythe Gentle Typhoons are very popular for their noise / performance (by far the best), Yate Loons perform well and are cheap. You can double up on the fans for an extra 20-30% performance boost

CPU block: EK Supreme HF for performance, XSPC Rasa for price / performance.

GPU block: Full cover or GPU only. Full cover are expensive, only work on one particular card, look nice and cool the Ram / MOSFETS. GPU only blocks provide better core cooling, are cheaper, work on many cards (can keep same GPU block after an upgrade) but require a cooling solution for Ram / MOSFETS.

Tubing: 3/8", 7/16" or 1/2" Internal Diameter (ID), personal preference. There is no real performance difference between the tubing sizes, pick what you like the look of. Go for the thicker wall tubes (3/8" x 5/8", 7/16" x 5/8" or 1/2" x 3/4") as these are more kink resistant. If you want colour then get some coloured tubing.

Fittings: Two per separate component (unless you are using a SLI connector for your GPU blocks). Barbs or compression, the only real differences are price and looks. With compression, match both the ID and OD of the tubing to the fitting. With barbs you should get some clamps, spring steel, plastic, worm clamps or even zip ties work. Match the tubing ID to the barb and the OD to the clamp. You can also run 7/16" tubing over 1/2" barbs for a cleaner look without needing clamps.

Coolant: Distilled water from the grocery store with a few drops of PT Nuke or a silver KillCoil to stop algae buildup.

Also depending on your budget, getting completely custom loops will cost you quite a bit ($300 ish for new parts) where the higher end RASA kits cost about $150 - $200.

The Rasa RX kits are nice.
I would highly recommend them.
I would really go custom loop though....
